What is the fewest number of points you must plot in order to have examples of all four sets of numbers, including at least one

Over [174]

Answer:

Let's define the sets:

Integers: The set of all whole numbers.

Rational: Numbers that can be written as the quotient of two integer numbers.

Natural: The set of the positive integers.

Whole numbers: All the numbers that can be made by adding (or subtracting) 1 a given number of times.

Then:

2 is a:

Whole number because 1 + 1 = 2 (then it is also a integer)

We can write 2 = 4/2

Then 2 is the quotient of two integer numbers, then it is rational.

2 is positive and is an integer, then it is a natural number.

Then number 2 is an example of all four sets.

If we also want to include a negative number, we can use -3

-3 is an integer, is a whole number, and 9/-3 = -3, then it is also a rational number.

Now, answering the questions:

a) We can use only one example for all four sets, but in this case i gave 2.

b) in the same way that i prove that 2, a positive integer, belongs to the four sets, we can do the same for every positive integer, then:

Positive integers belong to:

The set of integers.

The set of natural numbers.

The set of rational numbers.

The set of whole numbers.

Write down all elements of ({9, 10, 11} ∩ {10, 11, 12, 13}) ∪ {14, 15}. (enter your answer in set notation.)

iren [92.7K]

What we have so far:
Let set A = {9, 10, 11}
Let set B = {10, 11, 12, 13}
Let set C = A∩B. This means: the intersection of A & B.
Let set D = {14, 15}
Let set Universal = C∪D. This means: the union of C & D where C is the intersection of A & B.

Solution:
Let us first solve for set C.
C = A∩B
C = {9, 10, 11} ∩ {10, 11, 12, 13}
C = {10, 11} <--- New value for set C

Let us now solve for set Universal.
Universal = C∪D
Unviversal = {10, 11} ∪ {14, 15}
∴ Universal = {10, 11, 14, 15} <--- What we are looking for.

Therefore, the answer is Universal = {10, 11, 14, 15}.

X-y=3

ycow [4]

<h3>Question:-</h3>

If x - y = 3

Work out the value of 5(x - y)

<h3>Answer:-</h3>

x - y = 3 ( Given )

$\therefore$ 5(x - y) = 5 × 3 = 15 [ as x - y = 3 ]

_____________________________________

<h3>Question:-</h3>

If x - y = 3

Work out the value of 2x - 2y

<h3>Answer:-</h3>

x - y = 3 ( Given )

$\therefore$ 2x - 2y = 2(x - y) = 2 × 3 = 6 [ as x - y = 3 ]
